Thierry Henry has questioned Manchester United manager Louis van Gaal's decision to play Anthony Martial on the right wing.

Following his summer arrival from Monaco, the 20-year-old made an initial impression when he scored four goals in his first four outings for the club as a centre-forward.

However, since then, the France international has often been deployed out wide, where he has struggled to make as much of an impact.

His latest appearance as a wideman came during the weekend's 2-1 loss at home to Norwich City and speaking on Sky Sports News about the situation, Henry said: "What is he doing there? I actually do not know what he is doing there.

"He should be in the penalty area, having a one versus one, scoring and celebrating. Is it fear? Is it because they have been brainwashed a bit too much? I just don't get it.

"They wanted a guy who scored goals. They wanted a guy to run in behind fast. He came in and did that. Suddenly now he finds himself out there, almost not touching the ball. I think if I had a player like that, he would be my number nine and the rest are around him."

In total, Martial has found the net on seven occasions in a United shirt.
